Driver Side Door Entry Lock and Unlock Functions do not Operate: Procedure

1. When the door control switch on the multiplex network master switch assembly is operated, check that the doors unlock and lock according to the switch operation. Refer to OPERATION CHECK .

   OK

   Door locks operate normally.

NG → See step   7 

OK: Go to next step 

1. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly LH (for driver door) and perform an entry function check. Refer to OPERATION CHECK .

   *a	Approximately 0.3 m (0.984 ft.)

   NOTE:

   Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.657 ft.) of the door handle.

   HINT: 

   If the inspection result is that the problem only occurs in certain locations or at certain times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

   Entry function operates normally.	B

B → AFFECTED BY WAVE INTERFERENCE 

A: Go to next step 

1. Disconnect the Q1 front door outside handle assembly LH (for driver door) connector.
2. Disconnect the D64 certification ECU (smart key ECU assembly) connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Q1-3 (ANT2) - D64-13 (CG1B)	Always	Below 1 Ω
   Q1-6 (ANT1) - D64-12 (CLG1)	Always	Below 1 Ω
   Q1-5 (B) - D64-19 (POS1)	Always	Below 1 Ω
   Q1-2 (GND) - Body ground	Always	Below 1 Ω
   Q1-3 (ANT2) or D64-13 (CG1B) - Body ground	Always	10 kΩ or higher
   Q1-6 (ANT1) or D64-12 (CLG1) - Body ground	Always	10 kΩ or higher
   Q1-5 (B) or D64-19 (POS1) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the Q1 front door outside handle assembly LH (for driver door) connector.

2. Connect the D64 certification ECU (smart key ECU assembly) connector.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   Q1-5 (B) - Q1-2 (GND)	Engine switch off → on (IG)	9 to 12 V → Below 2 V

4. Using an oscilloscope, check the waveform.

   OK

   Tester Connection	Condition	Tool Setting	Specified Condition
   Q1-3 (ANT2) - Q1-6 (ANT1)	Procedure: Engine switch off Electrical key transmitter sub-assembly brought outside vehicle All doors closed Electrical key transmitter sub-assembly not inside vehicle Electrical key transmitter sub-assembly brought outside detection area* All doors locked through wireless operation	2 V/DIV., 500 ms/DIV.

NG → See step   8 

OK: Go to next step 

1. Temporarily replace the front door outside handle assembly LH (for driver door) with a new or known good one. Refer to DISASSEMBLY .

NEXT: Go to next step 

1. Check that the entry functions operate normally. Refer to OPERATION CHECK .

   OK

   Entry functions operate normally.

NG → See step   9 

OK → END (FRONT DOOR OUTSIDE HANDLE ASSEMBLY LH (FOR DRIVER DOOR) WAS DEFECTIVE)
